1PowerMockito can also be used to mock static methods. For example, let’s say you have a class that uses the static method System.currentTimeMillis() to get the current time. If you want to test that the method is called correctly, you can mock it:2package samples.powermockito.junit4.staticmocking;3import org.junit.Test;4import org.junit.runner.RunWith;5import org.powermock.core.classloader.annotations.PrepareForTest;6import org.powermock.modules.junit4.PowerMockRunner;7import static org.junit.Assert.assertEquals;8import static org.powermock.api.mockito.PowerMockito.mockStatic;9import static org.powermock.api.mockito.PowerMockito.when;10@RunWith(PowerMockRunner.class)11@PrepareForTest(System.class)12public class StaticMockingExampleTest {13    public void testStaticMethodMocking() {14        mockStatic(System.class);15        when(System.currentTimeMillis()).thenReturn(123456789L);16        assertEquals(123456789L, System.currentTimeMillis());17    }18}
